Diamond cutting discs for concrete

The new top-quality product from RHODIUS is not just for concrete

The diamond cutting disc RHODIUS LD300 with turbo rim offers an impressively high cutting speed for a wide range of applications.

It delivers exceptionally high performance thanks to high-quality industrial diamonds and an optimum diamond concentration. The RHODIUS LD300 comes with 12mm laser-welded diamond segments and a special design for exceptionally fast transport of the cutting particles away from the disc. The result: much less undercut, much less wear and a long service lifetime.

The disc has been specially developed for use on the angle grinder and machines of any power can make full use of its strengths (especially machines with a rated power of 1,400 kW and above). The RHODIUS LD300 diamond cutting disc is also available in diameters of 115mm and 125mm for the innovative X-LOCK changing system.

The LD300 handles abrasive, medium-hard and hard materials with ease

Whether hard bricks, reinforced concrete, steel concrete, concrete, paving bricks, hard stone, paving slabs, concrete pipes, kerbstones, medium-hard marble bricks, hard sand-lime bricks, hard concrete blocks, hollow concrete blocks, asphalt, fresh concrete or soft concrete blocks – the RHODIUS LD300 diamond cutting disc always delivers its full performance, impressing with a very fast cut and an outstandingly long service life.

Brick

Premium industrial diamonds are used to deliver consistently high quality with maximum cutting performance and speed. The industrial diamonds we use are produced synthetically from graphite under high pressure and temperature. A high-density, pore-free bond between the segments gives you high cutting speed combined with a long service lifetime.

Good to know

When mounting a diamond cutting disc, you must mount it in the specified direction of rotation, which is marked by an arrow on the disc. If mounted incorrectly, the disc can overheat very quickly and become blunt.
For dry cutting, think about taking breaks for the disc to cool off. For wet cutting, check that you have enough cooling. Overheating significantly shortens the lifetime of the disc and there is also an increased risk that the disc will break.
Working with concrete, asphalt, natural stone, brick, marble, tile and ceramics generates fine dusts. You must wear full protective clothing, including a mask.
The angle grinder typically ejects dust particles (and often larger pieces of material) to the rear. Please make sure that no one is working, walking or standing behind you and that there is nothing in the way that may be damaged.
When working with diamond cutting discs, do not apply too much pressure or let go of the machine. Avoid tilting it as well. One very important rule is that you must never use a diamond cutting disc for grinding!
We recommend always firmly clamping the piece of material to be worked on (such as a concrete tile). This reduces the risk of tilting and breaking the disc.
RHODIUS diamond tools are always perfectly matched to the material to be worked on. For abrasive to medium-hard materials, the slightly harder segment bond delivers optimum cutting performance with less wear.
The discs listed here have been specially developed for working on asphalt, concrete and stone. If you do need to cut metal from time to time, the RHODIUS DG210 ALLCUT is the alternative your need.
You can also sharpen a diamond cutting disc. If the cutting performance has noticeably decreased, several cuts down to segment height in an abrasive material such as sand-lime brick will help.

The right disc for every stone

A diamond cutting disc is the tool of choice in most cases for working, cutting and separating concrete, natural stone, tiles, ceramic and asphalt. However, if you want to work very quickly and cleanly, start by looking at the rim of your diamond disc.

For working in concrete, we recommend a diamond cutting disc with a segmented rim. A high-density, pore-free bond between the segments also gives you a particularly high cutting speed and a long service lifetime.
